Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the behavioral disclosure burden. It communicates a read-only browsing action and lists return fields, but it does not mention potential pagination, response limits, ordering, or error conditions. Still, no destructive or surprising behavior is hinted at.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loads the primary action, and packs optional filters plus return fields compactly. It avoids verbose or redundant language while staying informative.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description names the return contents, clarifies scope ('published'), and lists the available filters, which is sufficient for basic invocation. It does not mention pagination or ordering, but the tool's simple read-only nature makes this a minor gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already covers all four parameters, and the description adds minimal semantic value beyond restating the filters. It does clarify that query, category, and price are optional, which is useful, but it does not deeply enhance parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Browse') and the resource ('published Ordinal services'). It also distinguishes itself from related tools by emphasizing listing/browsing with optional filters, while sibling tools like call/try service would handle execution.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for discovering or filtering published services, but it does not explicitly state when to prefer this tool over siblings such as a service details tool or a test/call tool. It provides clear context ('published services') but no direct alternative guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
